[ Upstream commit 83f672a7f69ec38b1bbb27221e342937f68c11c7 ] When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to generate console output. That will continue to work even after debug_cons_nputs() becomes unavailable so there's no need to unregister the boot console. Take the opportunity to remove a repeated MACH_IS_* test. Use the actual .write method (instead of a wrapper) and test that pointer instead. This means adding an unused parameter to debug_cons_nputs() for consistency with the struct console API. early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late, head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol depend on the latter, to obviate some ifdef conditionals.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
